Hi 2320776962,
Are you using the devkit or custom board for Orin NX?
What’s your Jetpack version in use? (JP5.1.1?!)
From the screenshot you shared, it seems you use the wrong board config to flash.
Please share the result of the following command on your board and full flash log for further check.
$ cat /etc/nv_boot_control.conf
custom board，JP5.1.1
It is two identical orin nx devices. After backing up the A device system, it was successfully restored on the A device, but restoring the A device image to the B device failed
There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
Have you ever flashed the QSPI on B device before restoring the image on NVMe?
